New identities start with a low inlet quota that rises only after a history of honest, attested work, so a flood of fresh fakes cannot move real volume. Forging thousands of identities then costs capital per identity: copper-cheap fakes become basalt-expensive, and misbehavior burns the bond, so an attacker pays for every fake and loses the stake when caught.","stamp":0,"from":"poa12CDdKm4zu6Q53NpsKA3MC1usGYzYePGcVRqbCvq7HejQ","nonce":4,"parents":["9846d96dac12aa9a07b44bead3d447e31586dd072078b0e9df7e04ef9f6430f5","c12c1e68e484e5bed6ffc0c4af1f7729e6cc6e97aea218a470b09930c7ed2f47"],"ts":1792922592,"cid":"poa-mainnet-1","sig":"5fQUCWPPfypg6xXU9CGtmSZ3X2g4m38fcZUrbfqeSnS9rJ9wrZ65ukTFcNC7cde42Nw7jzkKCbTr9oemuGdUReAT"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:15:32.011Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
